Is the Sigma 14–24mm f/2.8 DN Art Mirrorless The New Sony FE Ultra-Wide Champion?

Sigma Art lenses have gained a reputation for being extremely sharp, indeed, they are ready for the next generation of high-megapixel digital cameras. Now, Sigma has taken it one step further, potentially disproving all the nay-sayers who claimed that high-end full-frame mirrorless lenses couldn’t actually be smaller (or cheaper) than their DSLR competitors.

The Sigma 14–24mm f/2.8 DG DN Art is made exclusively for the Sony E-mount and Leica L (Panasonic) mount, and it stands alone (currently) as the only full-frame ultra-wide f/2.8 zoom exclusively for full-frame mirrorless that achieves the highly desirable 14mm focal length.

Is it the right lens for you, though? Especially if you already have a DSLR ultra-wide zoom, (Sigma already makes a great one for both Canon and Nikon DSLRs) that is pretty impressively sharp? (Indeed, almost every wide-angle zoom lense these days is very sharp!) As much as we dislike adapters, this Sigma is still a ~$1400 investment…

Well, to spoil most of the review, just ask yourself these questions: are you addicted to sharpness and pixel-peeping? What about…
